Answer:
A is the answer
Step-by-step explanation:
because it is equal to the first triangle
It is 9 inches because 54 divided by 6 is 9
Answer:
90 between 1000 and 9999
Step-by-step explanation:
The first digit cannot be 0. It can be nine other digits.
The second digit can be anything between 0 and 9.
To be palindromic the 2nd and 3rd digits must be the same.
And in addition, the 1st and 4 numbers must be the same.
So the answer is 9 * 10 = 90. That does seem too small, but try making a palindrome with the restrictions I have outlined. None of the examples you have given beginning with 8 are palindromic.
8118 is palindromic
8998 is also palindromic
9009 is palindromic
2002 is palindromic
There are only 90 of them.
Answer:
a. $20.45
b. $24.55
c. $4.55
Step-by-step explanation:
In this question, we are asked to calculate the cost price and profit or loss selling a pair of shoes.
we proceed as follows
Firstly, we want to find the cost price given the selling price and the mark up percentage.
mathematically;
profit =( selling price - cost price)/cost price * 100%
here our profit is 120% with the cost price being $45. we plug these values
120 = 45-cp/cp * 100%
120cp = 100(45-cp)
120cp = 4500 -100cp
220cp = 4500
cp = 4500/220 = $20.45
His profit is selling price - cost price = 45 - 20.45 = $24.55
His profit selling same shoe for $25 is 25-20.45 = $4.55
Answer:
25 seconds
Step-by-step explanation:
You have a rate of:
![\dfrac{1}{5}gal/s](https://tex.z-dn.net/?f=%5Cdfrac%7B1%7D%7B5%7Dgal%2Fs)
And you want to find how many seconds it would take to fill in 5 gallons of water. Using the rate, we use it as a conversion factor from rate to seconds:
![5gal\times\dfrac{1sec}{\frac{1}{5}gal}=\dfrac{5sec}{\frac{1}{5}}=25sec](https://tex.z-dn.net/?f=5gal%5Ctimes%5Cdfrac%7B1sec%7D%7B%5Cfrac%7B1%7D%7B5%7Dgal%7D%3D%5Cdfrac%7B5sec%7D%7B%5Cfrac%7B1%7D%7B5%7D%7D%3D25sec)
